Rocks of Upper Rockridge

During my search for Rockridge Rock, I’ve been finding some fine Franciscan knockers doing their understated bit to add character to the neighborhood. Call this part 1, because I’ll surely find more as I pursue my search. These five rocks are shown in descending order of elevation. The first is at Buena Vista Avenue and Hill Road, a red chert.

This gray chert is on Bowling Westminster Drive, near the purported Rockridge Rock site on Glenbrook.
